How do I adjust the aperture value of the DSC-RX camera while recording a movie?

Changing the aperture value while recording movies may produce a clicking sound. This is normal operation. If the clicking sound is affecting the quality of the recorded movies, we recommend to use an external microphone, set Audio Recording to Off, or adjust Audio Rec Level.
